To ALL WHOM IT MAY coNonnNi Be it known that I, STEPHEN SARGENT, ofLowell, in the county of Middlesex, and Stat-o of Massachusetts, haveinvented certain new and useful Improvements' in'Oil Cans, of which thefollowing is a. full, clear, und exact description, reference being hadto the accompanying drawing, making part of this specification, inwhich- Figures 1 and 2 are vertical central sections, and

Figures 3 and 4 side elevations.

This invention consists in a suitable venting chamber, and a ventingtube connected therewith' at or near the bottom of said chamber,arranged at one side, and at the top of the oil can, or laround the baseof the oiling tube, when said oil can, venting chamber, and venting tubeare so constructed and arranged in relation to each theras to give freevent to the oil at all times, casyand convenient access to the venting`tube, if obstructed, and prevents oil escaping through the venting tube,under any circumstances.

In the drawings fig. 1 shows my improvement, with the venting chamber Aarranged at the extrelrc top of the oil can, and'around the oiling VtubeB, which screws into the can at the bottom of lthe chamber. The veutingtube C passes through the top part of the can, at one side of the oilingtube, or it may pass through the side of the oiling tube from within, asshown at Cz in red lines. The venting tube should terminate near thebottom of the can, at one side, or at the centre, as shown in figs. land2. When the venting chamber is arranged'as shown in fig. 1, I employ atube a., secured to the cap b, which screws into the top of the chamber.This tube surrounds the oiling tube B, a little distance therefrom, andextends downward to near the bottom oi' the chamber, so that if bycontinued use of the oil can small quantities of oil should rundown onthe outside of the tube B, through the space g, into the chamber A, suchoil will be retained in the chamber, between the tube a and the sides: hh of the chamber, to'run back into the oil can through the venting tubewhen said can is placed in a. vertical position. The space g around thetube B provides for `ingress of air to the chamber A, thence into thecan, through the tube C dr C2. y When the venting 'chamber is arrangedas shown in lig. 2 the top of said chamber is closed by a cap d, whichmay be removed to clear the tube .C by passing a wire through said tube,if at any time it should get choked. A tube c is also employed betweenthe cavity e in the cap f of the oilcan and the chamber A, vand extendsintosaid chamber to about thc centre. This tujbe or passage c providesfor ingress of air to the chamber A, thence to the interior of the can,through the tube C, and serves also for a passage back into the oilcanof any oil that may run down on the outside of the tube B, through saidpassage c, to the chamber A, and through the tube C into the oil can. Bythe arrangement of the venting chamber A, having a. small or contractedinlet g or c, for admission of air into the chamber, tipping the oil canso that oil will run out through the tube B causes a rush of air in atthe space q or the`tube c, through the chamber A and venting tube C, tothe interior of the can in quantity to compensate for the amount of oildischarged from within, thus providing free vent for the oil, 'andpreventing escape of oil througlnthe venting tube under anycircumstances, whether the venting chamber is arranged at the top of theoil can, around the oiling tube, as shown in iig. 1, or at one sideofthe oil can, as shown in iig. 2. It'is quite desirable iu small oilcans,

,oil can, the whole arranged substantially as and for the purpose setforth.

which are intended to hold only oil enough to last one day, to 'arrangethe venting chamber at the top of the can, as shown in iig. 1. The canmay then be lled full, and the precise quantity of oil used each day maybe known. l What I claim as new, and desire to secure by LettersPat-ent, is- 4 The combination of the venting chamber A, venting tube C,passage c or g, or their equivalent, with the STEPHEN SARGENT.
